Overview

Halogen-bond catalysis enables selective copolymerization of oxetane and anhydrides, suggesting new routes for polymer synthesis.

Key Points

  • High selectivity in ester linkage surpasses 99% with nonsymmetric iodine activation, and copolymerization yields diverse polyesters.
  • The study showcases a new iodine activation mode that optimally regulates the composition of the resulting polyesters.
  • Assessment of various cyclic anhydrides reveals broad applicability and customizable properties for the formed copolymers.
  • Implications suggest that tailored polymer properties can be achieved through systematic control of catalyst ratios.
